Collectible coins encompass a wide range of items, including numismatic coins, commemorative pieces, and error coins. The United States One Cent Penny is a notable collectible, particularly certain years or variations that carry historical significance. In 1863, trial coins or patterns were created to test new designs or compositions for circulation, often in limited quantities, making them highly sought after by collectors. These coins provide insight into the evolving design and minting processes of the U.S. currency system.
